Categories:	Polymer; Thermoplastic; Adhesives, Sealants, and Coatings; Thermoset; Polyurethane, TS
Material Notes:	Bayhydrol A 2457 is an anionic polyacrylic dispersion. It is suitable as a binder in the formulation of water-reducible two-component coatings and sealers for mineral substrates and reactive resins (EP, PU). Properties / Applications: Because of its outstanding mechanical and chemical resistance properties the product is ideally suited for the formulation of sealers for mineral substrates and reactive resins (EP, PU). Combination with other water-reducible binders is possible. Because of the many potential combination products, compatibility must always be tested. As with any product, use of Bayhydrol A 2457 in a given application must be tested (including but not limited to field testing) in advance by the user to determine suitability.
